I have a few Tv at home. 2 LG Tv and some other brand Tv too. One Tv dead pixel when i got it and one Tv dead pixel after 1 yr. I like LG because it has magic remote. Nowadays all Tv are not build to last. Just get a new Tv every 3/5 yrs.
Hi Henry,
You never mentioned which 2 TVs had defects, so I can't tell if LG is reliable or not.
When you look at reliability, we usually see the "bathtub" curve. Google it.
Basically, it means that most products either fail early during usage or late life. Early failure means around 1 year, late life would probably be somewhere after 3 years, but I think it can be 5 years or more.
Most would not complain when a product fails after maybe 5 years and would consider the brand reliable.
But when a product fails in a year, it either means you have bad luck or the particular brand have sloppy reliability test processes or engineering.
(our MRT system is a classic example of poor engineering)
IMO, a TV shouldn't fail within 5 years, unless it's a really budget model.
TV panels have easily 30000-60000hrs of life, that translates to 10-20 years of use at 8 hrs a day.
The electronics will more likely fail first, but should have a useful life of 5 years at least. They fail largely due to poor design, heat, lousy manufacturing quality. Again, if you buy a budget model, you get lousy engineering.
If a TV fails within 3-5 years, I would avoid the brand. Unless, it was a budget model, or a display set.
BTW, always avoid display sets, they run for more than 12 hours a day, for months and have experienced excessive heat in their useful operating life.
